Water pressure is a measure of the force that gets the water through our mains and into your pipes.
It is measured in 'bars' - one bar is the force needed to raise water to a height of 10 metres. We need pressure to push water through our pipes and into homes and businesses, whether they are in valleys, higher and hillier areas, or are raised like some flats and apartments.The amount of pressure at your tap depends on how high our service reservoir or water tower is above your home, or on how much water is being used by other customers.
Water pressure can vary at different times of the day. Pressure is normally higher late at night when very little water is being taken from our network and most people's taps are turned off. In the morning when people are taking a bath or shower, or watering their garden on a hot evening, there is a bigger demand for water which can cause low pressures.
The pressure also varies with the ground level. In hilly areas, the pressure will usually be high in the valleys, which are a long way below our reservoirs, and lower on the hilltops.
Water is much denser than air. A column of water 10 meters thick exerts the same amount of pressure as the entire Earth’s atmosphere (which is 80 miles thick!). That means if a diver descends just 10 meters underwater, he would experience the pressure of two atmospheres pressing down on every part of his body. If he were to descend to 20 meters, he would experience three atmospheres pressing down, and so on. The increased pressure changes the way gases behave in the diver’s body.
hope it helps ☺
